Method Summary

static java.util.HashMap	newMap(NamedObj namedObj) Given a NamedObj, generate a HashMap containing String key/value pairs where each key is a Variable contained in the namedObj argument, and each value is the value of the Variable.
static java.io.BufferedReader	openAsFileOrURL(java.lang.String inputFileName) Given a string that names a file, URL or resource, try to open as a file, and then as a URL, then as a resource.
static void	substitute(java.io.BufferedReader inputFile, java.util.Map substituteMap, java.lang.String outputFileName) Read in the contents of inputFile, and replace each matching String key found in substituteMap with the corresponding String value and write the results to outputFileName.
static java.lang.String	substitute(java.lang.String input, java.util.Map substituteMap) Given a string and a Map containing String key/value pairs, substitute any keys found in the input with the corresponding values.
static void	substitute(java.lang.String inputFileName, java.util.Map substituteMap, java.lang.String outputFileName) Read in the contents of inputFileName, and replace each matching String key found in substituteMap with the corresponding String value and write the results to outputFileName.
static java.lang.String	substitute(java.lang.String inputFileName, NamedObj namedObj) Read in the contents of inputFileName, and for each Parameter in namedObj, search for strings like @ParameterName@ in inputFileName, and substitute in the value of the Parameter and return the results.

Method Detail

newMap

public static java.util.HashMap newMap(NamedObj namedObj)
                                throws IllegalActionException

Given a NamedObj, generate a HashMap containing String key/value pairs where each key is a Variable contained in the namedObj argument, and each value is the value of the Variable.

Parameters:

namedObj - The NamedObj that contains Variables

Returns:

The HashMap consisting of key/value Strings.

Throws:

IllegalActionException - If there is a problem getting the Variables.

openAsFileOrURL

public static java.io.BufferedReader openAsFileOrURL(java.lang.String inputFileName)
                                              throws java.io.FileNotFoundException,
                                                     java.io.IOException

Given a string that names a file, URL or resource, try to open as a file, and then as a URL, then as a resource.

Parameters:

inputFileName - The name of the file or URL to open

Returns:

A BufferedReader that refers to the inputFileName

Throws:

java.io.FileNotFoundException - If the file cannot be found.

java.io.IOException - If there were problems creating the BufferedReader.

substitute

public static java.lang.String substitute(java.lang.String input,
                                          java.util.Map substituteMap)

Given a string and a Map containing String key/value pairs, substitute any keys found in the input with the corresponding values.

Parameters:

input - The input string that contains substrings like "@codeBase@".

substituteMap - The Map of String keys like "@codeBase@" and String values like "../../..".

Returns:

A string with the keys properly substituted with their corresponding values.

substitute

public static java.lang.String substitute(java.lang.String inputFileName,
                                          NamedObj namedObj)
                                   throws java.io.FileNotFoundException,
                                          java.io.IOException

Read in the contents of inputFileName, and for each Parameter in namedObj, search for strings like @ParameterName@ in inputFileName, and substitute in the value of the Parameter and return the results.

Parameters:

inputFileName - The name of the file to read from.

namedObj - The NamedObj that contains Parameters to be searched for in inputFileName.

Returns:

The contents of inputFileName after doing the substitutions

Throws:

java.io.FileNotFoundException - If the input file cannot be found.

java.io.IOException - If there is a problem creating the substitution map.

substitute

public static void substitute(java.io.BufferedReader inputFile,
                              java.util.Map substituteMap,
                              java.lang.String outputFileName)
                       throws java.io.FileNotFoundException,
                              java.io.IOException

Read in the contents of inputFile, and replace each matching String key found in substituteMap with the corresponding String value and write the results to outputFileName.

Parameters:

inputFile - A BufferedReader that refers to the file to be read in. This BufferedReader is always closed by this method.

substituteMap - The Map of String keys like "@codeBase@" and String values like "../../..".

outputFileName - The name of the file to write to.

Throws:

java.io.FileNotFoundException - If the input file cannot be found.

java.io.IOException - If there is a problem creating the substitution map.
